It is very hard for the mind to disengage itself from a subject on which it has been long employed. The thoughts will be rising of themselves from time to time, though we have given them no encouragement, as the tossings and fluctuations of the sea continue several hours after the winds are laid.

Addison.

403.

Hypocrisy will serve as well

To propagate a church as zeal;

As persecution and promotion

Do equally advance devotion:

So round white stones will serve, they say,

As well as eggs, to make hens lay.

Butler.
